Patent GB-927883-A (GB)
Abstract: 927,883. Measuring electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 3, 1961 [Feb. 5, 1960], No. 4132/61. Class 40 (1). The displacement of an inaccessible member for example a control rod in a nuclear reactor is determined by attaching to it a member 6 of magnetic material carrying a five start thread which may be used to drive the rod and which passes through three axially aligned transformers each consisting of a primary winding 1 and a secondary winding 5. A plan view of one of the transformers is shown in Fig. 2. The primary winding 1 has polepieces 9 set in a non- magnetic ring 12 of aluminium bronze. Similar polepieces 11 are provided for the secondary winding 5. A section through one of the transformers is shown in Fig. 3. The polepieces 18 are split as shown shaded and are aligned with the threads but the next pair of transformers are displaced axially so that the polepieces would align with the thread displaced 120 degrees from the position shown. The output voltages from the three secondaries are shown at 19, 19a, 19b. These voltages are fed through ferro-resonant circuits which produce pure sine waves from the harmonic-containing signal, pre-amplifiers 21 and rectifiers 23, 23a, 23b to give the voltage outputs indicated in the rectifier boxes. A steady negative voltage injected by sources 25 is subtracted from each of the signals in amplifier 24 to give signals 26, 26a, 26b which are applied to the windings of a " Magnesyn " (Registered Trade Mark) to indicate the value of the displacement.

Title: Remote display of objects and cursor movement in a conferencing system
Inventor: ROCCO MARTIN
IPC: G06F3/038

Abstract: An improved method and apparatus for remotely displaying cursor and tool operation in a conferencing system can be used for manipulating a remote cursor in a computer conferencing system, the computer conferencing system including a first participant coupled to a second participant via a communication medium. This process comprises the steps of: 1) selecting a remote cursor tool using the first participant's system, the remote cursor tool being a computer implemented function represented by an icon; 2) displaying the icon representing the remote cursor tool with an associated shadow only on the first participant's display and only while the tool is selected; 3) activating the remote cursor tool; and 4) displaying the icon representing the remote cursor tool without an associated shadow on both the first and the second participant's display only while the tool is active, the icon being displayed on a second display in a position corresponding to a position of the icon on a first display. The present invention also includes a process and an apparatus for implementing selected tool shadowing. This process comprises the steps of: 1) selecting a tool; 2) displaying the icon representing the tool with an associated shadow only while the tool is selected; 3) activating the tool to perform a function; and 3) re-displaying the icon representing the tool without an associated shadow only while the tool is active.
Patent GB-2294325-A (GB)
Title: Stylus attachment for a metrological instrument
Inventor: NETTLETON DAVID JOHN
IPC: G01B11/245
Filed: 1994-10-20
Abstract: An arrangement for mounting a stylus 9 shown as a stylus arm 43 on a stylus support 19 for a metrological instrument includes a camming pin 65 on a mounting disc 21 of the stylus support 19, which passes through a mounting hole 53 in a mounting disc 45 of the stylus 9. A spring 51 applies a sideways force to a sloping cam surface 71 of the camming pin 65, which is converted into a force pulling the camming pin 65 through the mounting hole 53 and thus holding the mounting discs 45, 21 together. An operator can deform the spring 51 so that it releases the camming pin 65, allowing the stylus 9 to be mounted or dismounted without applying significant force to the pivot bearing of the stylus support 19. If excessive radial force is applied to the stylus arm 43, the spring 51 will ride up the cam surface 71 allowing the stylus 9 to be released from the stylus support 19, thereby avoiding applying extreme forces to the pivot bearing. <IMAGE>

Patent GB-2301718-A (GB)
Title: PLL circuit
Inventor: IMURA MINORU
IPC: H03L7/10
Filed: 1996-03-26
Abstract: A PLL circuit is provided which has excellent quick response and noise resistance. A bias data memory circuit 7 previously stores frequency assignment data Da, for assigning the frequency of output signals S1 of VCO 1, as an address and the value, of a control voltage corresponding to the assigned frequency, as bias data Db. A bias voltage production circuit 6 produces a bias voltage Vb corresponding to the bias data Db. A switch control circuit 5 turns a switch 4 on to feed the bias voltage Vb to a capacitor 32 of a loop filter until the phase difference voltage Vd becomes close to the bias voltage Vb when the switch 4 is turned off. The switch 4 may be constituted by a transistor. The vco output may be changed by altering the reference frequency S2 or by a change of the division ratio of a variable frequency divider (not shown).

Title: A double superheterodyne receiver in which the first IF is chosen so that fluctuations in filter centre frequency are smaller than half a tuning step
Inventor: TOMIYAMA HITOSHI
IPC: H03D7/16
Filed: 1996-12-16
Abstract: An AM radio receiver according to the present invention is of double superheterodyne type. A first intermediate frequency is selected to be a low frequency of several kHz other than 0 kHz. A second intermediate frequency is selected to be several tens of kHz. A first local oscillator circuit formed of a PLL generates first local oscillation signals of two kinds whose phases differ from each other by 90{. First and second mixer circuits are respectively supplied with the first local oscillation signals of two kinds and mix them with received signals to generate the first intermediate frequency. First and second filters obtain signals each having the first intermediate frequency. A second local oscillator circuit generates second local oscillation signals of two kinds whose phases differ from each other by 90{. Third and fourth mixer circuits are respectively supplied with the signals having the first intermediate frequency and mix them with the second local oscillation signals. An adding circuit adds both of signals output from the third and fourth mixer circuits. A third filter is supplied with a signal from the adding circuit and obtains a signal having a second intermediate frequency. Then, an AM detecting circuit detects an amplitude of the signal having the second intermediate frequency to obtain an audio signal. The AM radio receiver has an IC incorporating an intermediate-frequency selecting device which operates as described above. The low frequency of the first IF ensures that fluctuations in the centre frequency of the following filters are smaller than half a tuning step so that the desired signal may be properly received.
